CAIRO  An Egyptian opposition party Monday claimed police tortured one of its members to death, electrocuting him and beating him repeatedly on the head — the latest case alleging police brutality in a crackdown on anti-government protesters.

Mohammed el-Gindy, a 28-year-old activist, died of his wounds early Monday at a Cairo hospital after he was “tortured to death,” the Egyptian Popular Current party said in a statement.

The Interior Ministry had no immediate comment.

El-Gindy disappeared for several days after protesting Jan. 27 in Cairo’s Tahrir Square. The protesters are opposed to Egypt’s Islamist President Mohammed Morsi’s policies and are pressing him to amend the constitution, which was drafted by a panel dominated by Islamists and approved in a public referendum last year.

Party spokesman Mona Amer said she saw el-Gindy’s body and that it carried marks of torture. She said he had been electrocuted, had broken ribs and a “cord appeared to have been wrapped around his neck.” A medical report cited brain hemorrhage as cause of death.

Party members were organizing a funeral for el-Gindy and Mohammed Saad, a 20-year-old protester, who also died of his wounds suffered during clashes with security forces Friday.
